About Us
Following many years experience of property administration in the local government sector I initially assisted former business associates with SAP calculations in a support role only, having set up as a sole trader in 2005.
I then undertook training with the National Home Energy Rating (NHER) Authorised SAP Assessor scheme in 2006 and subsequently passed their professional examinations in order that I could undertake SAP calculations independently. Working mainly with architects and developers, together with private individuals, I have a broad breadth of experience of providing SAP calculations for many different developments across the country and have worked on many schemes from single house for private individuals, through to major housing developments for some of the top twenty housebuilding companies.
In March 2008 my work was assessed as meeting the required level of competence to achieve direct entry to the NHER Accreditation Scheme for On Construction Domestic Energy Assessors (OCDEAs). This allows me to produce On Construction Energy Performance Certificates (OCEPCs) for newly constructed dwellings.
In October 2010 I undertook the mandatory NHER training scheme and examination to allow me to undertake SAP 2009 home energy rating calculations under Part L of the Building Regulations 2010 and this qualification has since been upgrade to cover SAP 2012 / Part L 2013.
As part of membership of the accreditation scheme I have professional indemnity insurance cover of £1.0m.
I retain my valued contacts with my former business associates and we operate independently as individual businesses but providing professional support, and assistance with peaks and troughs of workload, to each other, as necessary.This is under the umbrella of the EnergyRaters Network and we meet regularly for training and to share technical expertise.


I take pride in providing sound advice and services, combining technical excellence at reasonable prices.
